Chrysanthemum plant named ‘Yellow Yowoodstock’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yellow Yowoodstock’, characterized by its uniform and outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering response and habit; can be grown as a disbud or as a spray-type; early flowering habit; large anemone-type inflorescences; yellow-colored ray florets and enlarged yellow green to yellow-colored disc florets; and good postproduction longevity with plants maintaining good substance and color for about two to three weeks in an interior environment.

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yellow Yowoodstock.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Yellow Yowoodstock’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum cultivar Yowoodstock, disclosed in U.S. Plant patent application Ser. No. 10/396,576. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of flowering plants of Yowoodstock in April, 2001, in a controlled environment in Fort Myers, Fla. The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in July, 2001. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yellow Yowoodstock has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yellow Yowoodstock’. These characteristics in combination distinguish ‘Yellow Yowoodstock’ as a new and distinct Chrysanthemum:

-   -   1. Uniform and outwardly spreading plant habit.     -   2. Strong and freely branching growth habit.     -   3. Dark green-colored foliage.     -   4. Uniform flowering response and habit.     -   5. Can be grown as a disbud or as a spray-type.     -   6. Early flowering, eight week response time.     -   7. Large anemone-type inflorescences.     -   8. Yellow-colored ray florets and enlarged yellow green to         yellow-colored disc florets.     -   9. Good postproduction longevity with plants maintaining good         substance and color for about two to three weeks in an interior         environment.

Plants of the new Chrysanthemum can be compared to plants of the parent, the cultivar Yowoodstock. Plants of the new Chrysanthemum differ from plants of the cultivar Yowoodstock primarily in ray floret coloration as plants of the cultivar Yowoodstock have white-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Yellow Blush, disclosed in U.S. Plant Pat. No. 9,455. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yellow Blush primarily in inflorescence form as plants of the cultivar Yellow Blush had daisy-type inflorescences.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown and flowered during the winter in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, the following conditions were measured: day temperatures, 21 to 27° C.; night temperatures, 17 to 19° C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cm containers, exposed to long day/short night conditions, and pinched once about two weeks later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
